In the drawings, the portions indicated by solid lines are the portionsfor which a patent as a partial design is sought. The portions of thedrawings illustrated with broken lines are not part of the claimeddesign.

In the drawings, the left side view is omitted because it issymmetrically shown in the right side view.

A bearing for a wheel supports a wheel of an automobile in a rotatablemanner, and transmits a driving force of an engine or a motor to thewheel. A shaft portion of an outer joint member that configures aconstant velocity universal joint is press-fitted into an innercircumference of a hub wheel. The inner circumference of the hub wheelhas a female spline-shaped female teeth portion formed thereon, andafter press-fitting the shaft portion of the outer joint member, atorque transmission between the shaft portion and the hub wheel isperformed by a male spline-shaped male teeth portion formed on an outercircumferential surface of the shaft portion meshing with the femaleteeth portion. The female teeth portion of the hub wheel is composed ofa fitting portion on an axially front side and a guide portion on anaxially back side. Recess portions of the female teeth portion thatextend in an axial direction have greater width and depth at the guideportion than at the fitting portion. A module M, defined by M=PCD[mm]/Z, of the female teeth portion is set to be smaller than 1.0. Inthe formula, “Z” represents number of teeth.

CLAIM The ornamental design for a bearing for a wheel, a part of abearing for a wheel, and a hub wheel of a bearing for a wheel, as shownand described.
